ENVELGP-OPENER.

Application filed February 24, 1921.

To aZZ whom it may concern.

. Be it known that I, BASYL Fnnonno, a citizen of Ukraine, residing at Ansonia, in the county of New Haven and State of Con necticut, have invented certain new and uset'ul Improvements in Envelop-Openers, of which the following is a specification.

This invention relates to attachments for envelops for the purpose of expediting the opening of the same, and has for one of ts objects to improve the construction and increase the eiiiciency and utility of devices of this character.

Another object of the invention is to provide a simply constructed device which may be readily applied without material change of envelops of various sizes and forms, and which may be readily transferred from one envelop to another, or from an envelop which has been opened to an unused envelop, so that the device may be repeatedly used.

Another object of the invention is to provide a simply constructed device whereby an envelop may be quickly opened without injuring the contents of the same.

WVith the above general objects in view and others that will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described in connection with the accompanying drawing and in which like reference characters designate corresponding parts throughout the several views. 7

In the drawing,

Figure 1 is an elevational view of an envelop sealed or closed with the improvement constituting the present invention, applied,

Fig. 2 is a top view thereof,

Fig. 3 is a fragmentary elevational view of an envelop and the device of the present invention as it appears when the envelop is being opened, and

Fig. 4 is a perspective view of the envelop opener.

The present envelop opener may be applied to envelops of various sizes and forms and without mutilating the envelop, but for the purpose of illustration, it is shown applied to a conventional envelop involving the usual body portion composed of a front member with a back 5 and end flaps 6 and 7, as well as a closure flap 8.

The improved attachment comprises a strip of flexible material, such as relatively thin sheet metal and embodies a blade 9 hav- Specification of Letters Patent.

mg an upper sharpened edge 10 and provided wlth a stirrup 11 at one end which merely comprises a folded-over lug provided on said end of the blade. The blade 9 is provided with a laterally projecting lug 12 adjacent ts other end, and this lug as well as the adacent end portion of the blade indicated at 13 is adapted to be bent for a purpose and in a manner which will presently be made apparent, 1t being noted that the end 13 and lug are formed of suflicient strength and the like to cause them to firmly remain in bent position.

When an envelop is to be equipped with the present device, the stirrup 11 is disposed upon the upper edge of the letter 14 which is contained within the envelop so that the blade 9 is supported adjacent the. fold line between the closure flap 8 and the front of the envelop body. The device is then slid toward the adjacent end of the envelop so as to pierce it at the fold l1ne between one of the flaps 6 or 7 and the front of the envelop body so that said end pro ects outwardly. This end is then bent upon itself to engage the desired outer face of the envelop as shown in Fig. 1, the lug 12 is then directed through the envelop at the fold line of the flap 8. The lug 12 is then also bent upon itself to engage the outer face of the flap 8 as is also shown in Fig. 1 and the flap 8 is then sealed. In this position, the device does not cause the envelop to appear bulky or cumbersome and the presence of the opener is not perceptible from an unsightly standpoint, the only difference in the appearance of the envelop being the presence of the folded end 13 and lug 12. It will also be noted that the letter is utilized to support the blade adjacent the fold line of the flap 8, so that when the end 13 and lug 12 are unfolded to the dotted line position of Fig. 1, they may be utilized as finger pieces for upwardly tilting the device so as to. sever the envelop along the fold line of the flap 8 upon movement of the opener along the upper edge of the letter, and with out danger of mutilating the letter. It will be observed that the upward tilting movement of the opening device is readily accomplished' by the fulcruming of the stirmp 11 upon the upper edge of the letter. Thus. the opening operation is quickly accomplished, and if desired, the device may be retained for application to another envelop.

Patented nee. so, 1921.

From the fore oin descri tion it is believed that the construction and operation as well as the advantages oi the present 1nvention willbe readily understood and appreciated by those skilled in the art. Minor changes may be made without de parting from the spirit and scope of the infor severing the envelop along the fold line of said closure flap;

2. An envelop opener comprising a metal blade havlng a stirrup at one end tor engagement with the upper-edge of a letter so as to support the blade adjacent the fold line of an envelop closure flap, the blade having its other end formed to be projected through the fold line at one side of the envelop, whereby said end may be engaged for upwardly tilting and sliding the blade for severing the envelop along the fold line of said closureilap, said projecting end of the blade bcin flexible so as to be bent u on the envelop, and the blade end being or" such material as to insure remaining of the end in folded condition aswell as to permit unfolding of the same.

3. An envelop opener comprising a metal blade having a stirrup at one end for engagement with'the upper edge out a letter so as'to support the blade adjacentthe fold line of an envelop closure flap, the blade having its other'end formed to be projected through thei'old line 'at one side of the envelop,

' whereby said end may be engaged for up wardly tilting and sliding the blade for severing the envelop along the fold line of said closure flap, said projecting end of the blade 7 beingflexible so as to be bent upon the envelop, andthe blade end being of such material as to insure remalning of the end 1n vfolded condition as well as to permit unfolding oi the same, said blade being provided with a laterally projecting lug adjacent its projecting end adapted to be forced through the envelop at the fold line of the closure flap of the same, and said lug being also bendable or foldable against the to open the envelop.

4:. An envelop opener including a blade having a sharpened edge and provided with a stirrup at one end for reception of the upper edgeof a letter whereby the blade is supported substantially parallel with the upper edge of the letter and within the fold of the closure. flap of the envelop, and a member upon the opposite end of the blade accessible from the exterior of the envelop for manipulating the blade to sever the enygelop along said told line of the closure 1 ap. a,

5. An envelop opener including a blade having a sharpened edge and provided with a stirrup at one end for reception of the upper edge of a letter whereby the, blade is supported substantially parallel with the upper edge of the letter and within the fold oi the closure flap of the envelop, and a member upon the opposite end of the blade accessible from the exterior of the envelop for manipulating the blade to sever the envelop along said fold line of the closure flap, said accessible member including a laterally projecting lug carried by the blade and arranged to beflt'orced through the envelop at the closure flap 'fold line. 7

6. An envelop opener including a blade having a sharpened edge and provided with a stirrupat one end for reception of the upper edge of a letter whereby the blade is supported substantially parallel with the upper edge of the letter and within the fold of the closur'e'fiap' of the envelop, and a member upon the opposite end of the blade accessible from the exterior of the envelop for manipulating the bladeto sever the en-' velop along said fold line "of the closure flap, said accessible member including a lat-- erally projecting lug carried by the blade and arranged to be forced through the en velop at the closure flap fold line and said lug being bendable upon itself to engage the outer face ofthe closure flap. s

in testimony whereof I afiix my signature in presence of two witnesses.
